Abstract

The invention discloses a hydraulic energy-supply testing device with an air pressure-increasing valve. The hydraulic energy-supply testing device is characterized in that the hydraulic energy-supplytesting device comprises a servo motor, a high-pressure pump, a hydraulic oil storing container, a hydraulic oil pressure gauge, a hydraulic oil flow meter, a first pressure-adjusting valve and a second pressure-adjusting valve; hydraulic oil in the hydraulic oil storing container passes through the high-pressure pump driven by the servo motor and then passes through the hydraulic oil pressure gauge, the hydraulic oil flow meter and the first pressure-adjusting valve to form a high-pressure oil supply pipeline; two pipelines connected with oil discharging outlets of a hydraulic motor assemblyand a hydraulic pump assembly of the hydraulic energy-supply testing device in an automobile brake system are connected in parallel, then connected with the second pressure-adjusting pressure in series and connected with the hydraulic oil storing container; and the air pressure-increasing valve is arranged on the hydraulic oil storing container. The air pressure-increasing valve has the effects that bubbling of oil liquid in the hydraulic oil storing container is minimized, the situation that the hydraulic oil storing container is damaged by the vacuum or the over pressure is prevented, the working condition of the hydraulic pump is improved, and air plugging is avoided.

Description

technical field [0001] The invention relates to a performance testing device of an automobile braking system, in particular to a hydraulic energy supply testing device of the automobile braking system. Background technique [0002] The braking system of the car is to let the moving car slow down or even stop according to our wishes. The working principle is to convert the kinetic energy of the car into heat energy through friction. The automobile braking system is mainly composed of a hydraulic energy supply device, a control device, a transmission device and a brake. The common brakes mainly include drum brakes and disc brakes. [0003] Drum brakes mainly include brake wheel cylinders, brake shoes, brake drums, friction plates, return springs and other parts. Mainly through the hydraulic device, the friction plate rubs against the inner surface of the brake drum that the old wheel rotates, so as to achieve the effect of braking. When the brake pedal is stepped on, the pi...
